Brewers Dried Yeast With Vitamins Powder Supplement for Dogs and Cats
Verified Jun 15, 2026
This is a yeast-based powdered supplement for dogs and cats designed to support skin and coat health. It provides brewers dried yeast along with several B vitamins and vitamin C, which can help support normal skin function and overall vitality. It’s meant to be sprinkled on top of your pet’s regular complete and balanced diet, not used as a stand-alone food.
Nutritionally, this is a straightforward brewers yeast and vitamin supplement meant to complement your dog or cat’s regular diet. The B vitamins and vitamin C can support skin, coat, and general metabolic health when used appropriately. It’s best suited for otherwise healthy pets who are already eating a complete and balanced food and might benefit from a modest boost of yeast-derived nutrients and B vitamins.

KibbleLab Review
Strengths
- Simple, focused formula based on brewers dried yeast, which naturally provides B vitamins and other nutrients that can support skin and coat health.
- Added B-complex vitamins (thiamine, riboflavin, niacin) and vitamin C to further support normal metabolism and tissue health.
- Powder form makes it easy to sprinkle on existing food for both dogs and cats, with clear weight-based dosing and calorie information provided.
- Intended as a supplement, which gives flexibility to use alongside a variety of complete diets without drastically changing the pet’s main food.
Considerations
- Not a complete and balanced diet, so it must only be used on top of a regular, nutritionally complete pet food.
- Contains garlic, which some sensitive pets or those with certain medical conditions may need to avoid; discuss with your veterinarian if your pet has anemia or other blood-related issues.
- Yeast-containing products can occasionally bother pets with yeast-related skin or ear issues, so if your pet has a history of those problems, monitor closely or consult your vet before using.
- Adds extra calories, which are modest per teaspoon but should still be factored in for pets that need strict weight control.

Top 5 Ingredients Explained
01
Brewer's Yeast
Brewer's yeast (deactivated Saccharomyces cerevisiae) is commonly used in dog and cat foods as a flavor enhancer and supplemental source of protein, B‑complex vitamins, trace minerals and immunomodulating components such as beta‑glucans. It can support skin, coat and general nutritional status, but may cause gastrointestinal upset or allergic reactions in yeast‑sensitive pets, is not a live probiotic, and should be used cautiously in animals prone to purine‑related issues or those receiving antifungal medications.
02
Garlic
Garlic is sometimes used in pet foods as a flavoring or for claimed immune or antiparasitic effects, but it is not an essential nutrient for dogs or cats. Because garlic (and other Allium species) contains compounds that can cause oxidative damage to red blood cells and potentially trigger hemolytic anemia—cats are particularly sensitive—its inclusion is controversial and exposure should be avoided or discussed with your veterinarian.
03
Natural Flavor
Natural flavor is used primarily as a palatability enhancer in pet foods to improve taste and aroma and is not intended to provide significant nutrients, typically coming from concentrated extracts of meat, poultry, plant, or fermentation sources. While it can increase acceptance in picky dogs and cats, manufacturers are not required to disclose specific sources so pets with known sensitivities or allergies may react, and presence of natural flavor should not be taken as a guarantee of overall product quality.
04
Microcrystalline Cellulose
Microcrystalline cellulose is an insoluble, non-digestible fiber commonly used in pet foods as a bulking agent, binder and texture modifier and to prevent caking. For dogs and cats it can help add bulk for weight management and improve stool firmness without adding calories, but it supplies no digestible nutrients or fermentable prebiotics, so high levels can dilute nutrient density and may affect palatability; it is generally regarded as safe when used appropriately.
05
Niacin
Niacin (vitamin B3) is a water‑soluble B vitamin included in pet foods as an essential nutrient for energy metabolism and for maintaining healthy skin, nervous system, and digestive function. Dogs can make some niacin from tryptophan, but cats have a limited ability and therefore need sufficient dietary niacin; deficiencies cause poor growth, dermatitis and gastrointestinal or neurological signs, while very high supplemental doses can cause gastrointestinal upset or, rarely, liver issues, so it is normally provided at balanced levels in vitamin premixes.
